These grilles do not fully cover the grille opening, and they leave a gap at the top and bottom. On the front of the bonnet, just under the front air intakes, there is a long chrome strip with Nissan on it. On the side of the bonnet the slots have a chrome strip that runs horizontally through the middle of slot.
The engine used in the Nissan 580 is the same engine that was introduced in the previous Nissan 482 model, which was the NC series 3960cc 105hp 6 cylinder unit. A longer wheel base model, the G580 was also available, which was an extra 1000mm longer between the wheels. The bus version of the 580 was called the Nissan 590, and it was introduced six months before the 580 truck, in May 1955. A diesel engine version was also built called the M580.
In 1958 a new version of the Nissan 580 was introduced, called the Nissan 582. Mechanically the 582 was the same as the 580, the only notable differences being to the grille and trim. The grille on the 582 is much taller than that on the 580, and it now fills the whole grille opening, rather than leaving a large gap at the top and bottom like the 580. The 580 grille was fairly straight and angular, while the new 582 grille is much more rounded. Also in the side of the bonnet the trim has changed. On the 580 the slot on the side of the bonnet has a horizontal strip this travels through the middle of the slot, on the 582 the strip sits on top of the opening slot.
The Nissan 582 was the last vehicle in this body shape that first began with the Nissan 380 in 1952. The 582 was replaced in March 1959 with the all new Nissan 680.
